ASX-listed Askari Metals has reviewed the historical exploration database for its Uis project, in Namibia, with the focus on evaluating the significant tin and tantalum mineralisation that exists.

Data review has initially focused on EPL 8535 being the southernmost tenement owned by Askari, located about 14 km from the London-listed Andrada Mining’s operating Uis tin mine.

Historical exploration has highlighted exceptionally high-grade tin, tantalum and rubidium mineralisation at the Uis project, Askari states.

Mapping and rock-chip sampling at the Kestrel pegmatite target has demonstrated high-grade mineralisation.

The Kestrel pegmatite has a strike length of about 3 km and is up to 30 m wide.

The database includes 492 rock-chip samples with assay results including tin oxide up to 3.17% and tantalum oxide peaking at 5 226 parts per million.

Historical drilling, which has never been followed up on, demonstrated high-grade mineralisation, the company highlights.

Askari says the Uis project is emerging as a strategic asset offering polymetallic mineralisation including tin, tantalum, lithium and rubidium.

The strategic location of the project along strike of the operating Uis mine underpins the significant value-add opportunity that exists and highlights the importance of this region, it adds.

“The Uis project is truly a polymetallic project offering significant economic upside. In an environment where the tin price is currently trading at $31 275/t, the opportunity for Askari to follow up on previous exploration focused on developing the tin potential of the Uis project is too hard to ignore,” Askari director Gino D’Anna says.

“The Uis project represents a heavily underexplored opportunity and includes some spectacular historical exploration results which identified high-grade tin and tantalum mineralisation. These results demonstrate the significant exploration potential of the project area.

“Our initial exploration efforts have identified further high-grade tin and tantalum mineralisation at surface and in drill holes extending the zone of known mineralisation on EPL 8535. The company is excited to begin further exploration of these new targets. . .,” he adds.
